Diesel Engines Quiz

What is the function of the crankshaft in a diesel engine?

• Converts heat energy into reciprocating motion

• Controls and powers the electric motor used to start the engine

• Transfers reciprocating motion from the valve lifter to the rocker arm

• Drives the camshaft gear or idler gear

What is the purpose of the oil pump in a diesel engine?

• Circulates air and liquid to transfer heat away from the engine

• Reduces friction by providing lubrication around and between moving parts

• Pressurizes oil to circulate it to rotating and reciprocating parts

• Produces, controls, and monitors electrical current needed while the vehicle is running

What is the function of the piston in a diesel engine?

• Drives the camshaft gear or idler gear

• Transfers reciprocating motion from the valve lifter to the rocker arm

• Controls and powers the electric motor used to start the engine

• Converts heat energy into reciprocating motion

What is the purpose of the cylinder head in a diesel engine?

• Seals the top of the cylinder and contains coolant passages, injectors, and valves

• Pressurizes oil to circulate it to rotating and reciprocating parts

• Circulates air and liquid to transfer heat away from the engine

• Stores momentum, smoothes out firing pulses, and carries the crankshaft around to the next firing pulse

What is the function of the intake valve in a diesel engine?

• Opens a port in the cylinder head to allow the spent exhaust gases to be forced from the cylinder

• Rides on the cam lobe, converting the cam's rotary motion into reciprocating motion

• Transfers motion from the push rod to the valve

• Opens a port in the cylinder head to allow the fresh air charge to be drawn into the cylinder

What is the purpose of the oil cooler in a diesel engine?

• Cools and regulates the oil temperature

• Stores momentum, smoothes out firing pulses, and carries the crankshaft around to the next firing pulse

• Reduces friction by providing lubrication around and between moving parts

• Circulates air and liquid to transfer heat away from the engine

• Rides on the cam lobe, converting the cam's rotary motion into reciprocating motion

What is the purpose of the flywheel in a diesel engine?

• Stores momentum, smoothes out firing pulses, and carries the crankshaft around to the next firing pulse

• Pressurizes oil to circulate it to rotating and reciprocating parts

• Converts heat energy into reciprocating motion

• Controls and powers the electric motor used to start the engine
